SEAT.

SPECIFICATION forming part of Letters Patent No. 370,029, dated September 13, 1887.

Application filed October 17, 1883. Serial No. 109,298. (No model.)

To aZZ whom it may concern.-

Be it known that I, ALoIs WINKLER, a citinen of the United States, residing at Oneonla, 1n the county of Otsego and State of New York, have invented certain new and useful Improvements in Seats, of which the following is a specification, reference being bad therein to the accompanying drawings.

Figure 1 is a side elevation of a seat having my invention applied thereto. Fig. 2 is atop plan view of a portion of the seat. Fig. 3 is a section on the line 00 as, Fig. 2. Fig. 4 is a plan view, enlarged, illustrating myinvention. Figs. 5, 6, 7, 8, and 9 are perspective views of different forms of clamping devices embodying the inventions herein claimed. Fig. 10 shows a modification of the seat-frame.

This invention relates to certain improvements upon that form of device for securing slats to a seat-frame which is shown, described, and generically claimed in another application of mine, Serial No. 43,054, filed October 3, 1881, to which application reference is made for a fuller understanding of my invention.

In the drawings, A represents a portion of the seat-frame. This may be either in the form of a bar adapted to be secured to or cast with legs B or other base, as shown in Fig. 1, or this part A may be in the form of a flange upon the top of a bar, as shown in Fig. 10.

A represents the back of the frame, which may be an independent bar secured to the seat-frame, as shown in Fig. 1, or may be cast with or secured thereto, as shown in Fig. 10.

0 represents the slats, which are united to the seat frame and back by means of clamping devices, each having a bar or pin adapted to be inserted into an aperture in the edge of the slat, and a hooked arm adapted to engage with the slat-support of the seat-frame.

The operation of putting together a seat by the use of my invention will be understood by an examination of the drawings, and is further fully described in my aforesaid application No. 43,054, and need not therefore be herein set forth.

The features of invention to which this application is limited consist of a clamp the slatengaging bar or arm of which is separable from the slat-support-engaging arm, and, secondly, of a clamp having a slat-engaging bar and a single frame-engaging bar projecting laterally from one side of the slat-engaging bar, in contradistinction to a frame-bar having two arms projecting in opposite directions laterally from the slat-bar, and to certain fea tures of construction pointed out in the claims.

it represents the bar or pin,which is adapted to be inserted into an aperture in the edge of a slat. (See Fig. 4.) In the construction shown in Fig. 5 this bar It is circular in crosssection, and is adapted to be seated in a correspondingly-shaped aperture, h, formed in the part of the clamp which engages with the slatsupport. This last-referred-to portion of the .clamp consists of an arm, '5, extending outward and at substantially a right angle from part h, and having a hooked part, 7 adapted to engage with a face of the slat-support other than that on which the slat rests, thus uniting it with the seat-frame, the seat-frame being shown as provided with a flange, a, wherewith the book i engages. The pin it may be of alength sufticient to engage with two slats, its ends in such case proj eating in opposite directions from the hookt' i, or it may project from one side only of the hook and be adapted to engage with but one slat.

The'construction of clamp shown in Fig. (5 is similar to that shown in Fig. 5, except that it has two hooked arms, 1. i, on opposite sides of the pin h, whereby it is adapted to engage with the seat-frame at two points, thereby more securely uniting the slats to the seatframe than when a clamp like that in Fig. 5 is used, and also preventing any possible rotation of the clamp.

In Fig. 7 the pin h and the aperture h, in which it is seated,are angular in cross-section. In such case the apertures in the edges of the slats are correspondingly shaped. This constructiou, by reason of the angular form of the pin h, prevents rotation of the clamp after it has been engaged with the slat.

It is not necessary that the seat 71. in the frame-engaging part of the clamp should be an eye or entirely surround the pin h, for it may be constructed substantially as shown in Fig. 8, wherein the part h passes under the frame-engaging part, as will be seen without further description.

In Figs. 5, 6, and 7 I have shown the part of the frame-engaging portion of the clamp through which the slat-engaging part passes as expanded or elongated, whereby there is formed a hub, h which serves to space the slats, this hub being of any desired length.

In Fig. 10 there is shown a form differing from that shown in my said other application, No. 43,054, in that it dispenses with one-half of the frame-engaging bar, and has only a single hooked arm projecting from the slat-bar h, and differing from that in Fig. 7 in having the slat-bar and the framearms cast integral.

Of the several features of construction shown herein some can be used with or without those which are made the subject-matter ofthe claims herein. Concerningsuch features as are not herein claimed, I reserve the right to present claims in my other application, No. 247,581, filed August 23, 1887, wherein I have shown modifications of the invention; nor do Iherein claim any of the subjects-matter of the claims in my earlier application, No. 43,054, filed Octob'er 3, 1881, also pending herewith.

WVhat I claim is- .1. The hereindescribed clamping device adapted to unite slats to a seat-frame, it consisting ofa slat-engaging bar or pin, h, and a hooked arm formed separately from pin h and adapted to engage with the slat-support, substantially as set forth.

2. The .herein described clamping device adapted to unite slats to a seat-frame, it consisting of a hooked arm adapted to engage with the slat-support and being perforated, as at h, and a slat-engaging bar, h, adapted to be seated in said aperture or perforation, substantially as set forth.

3. A clamping device adapted to unite slats to aseat-frame,it consisting of a slat-engaging bar, h, and a single frame-engaging hooked arm, 13, projecting laterally from the bar h, in

contradistinction to a frame-engaging bar havas at h, whereby there is formed a hub which serves to space the slats, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses. V
